JBL CSA 2300Z Power Amplifier

Innovation and Invention - The JBL CSA 2300Z Power Amplifier

By combining years of insight from HARMAN brands, JBL Commercial Series Amplifiers (CSA) go well beyond the expected in generating powerful sound. The efficient performance of Crown’s DriveCore Technology continues to set new standards in commercial power amplifier technology. Simple to configure, the Commercial Series amp provides a DriveCore-based sound solution. This replaces up to 500 parts with one small chip, significantly reducing the part count and increasing reliability while maintaining superb performance.
